TRANSMISSION ISOLATION MOUNT
FWD / LATERAL RESTRAINTS
[ELASTOMERIC DAMPERS]
TRANSMISSION INSTALLATION
The transmission attaches to the airframe
through TWO fluid filled [a highly viscous
synthetic silicone liquid] mounts to reduce
airframe vibrations. The elastomeric pads at the
transmission fittings provide vertical softness.
Transmission pitch and roll restraint and the
allowable motion envelope are controlled by
dual FWD/AFT and LATERAL elastomeric
dampers. Each isolation mount has a visual
inspection port which permits observation of
the correct fluid level within the sealed
assembly.
